Specification of Letters Patent.

Application filed April 14, 1913.

Patented Nov. 18,1913.

Serial No. 760,882. i

T all whom it may concern:

lie it known that I, OSCAR M. PANNIER, a citizen of the United States,residing at Pittsburgh, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inStamps, of which the followingis a speciiication.

My invention is an improvement in the class of stamps, similar to rubberstamps, and adapted to mark any suitable surface with an imprint bymeans of raised letters extending beyond the supporting base or surface.a series of such being removablv mounted upon a supporting. framework,suitably curved to provide for a rolling or rocking action of the device.as. used by the operator.

The invention has in view to provide .a

stamp of this character for hand use, in connection with a suit-ableinking pad.

The principal object of the invention is to provide in a device of thischaracter, a manipulable base having a curved supporting and attachingbottom, preferably slightly resilient, adapted to receive the severalremovable and attachable units, the base and printing units beingconstructed and ada ted for easyand quick changing of the units, and forfixedly holding them upon the base, the printing units also beingconstructed in a novel manner for facilitating the carrying out of theirdesired function, in the manner more fully hereinafter described.

In the drawings illustrating .preferrcd form's of'the invention, Figure1 is an under plan view of-the stamp showinga portion of its lengthprovided with printing units. Pig. 9 is a view of the device in sideelevation. Fig. 3 is a CI'OSSfSQCtIOIl taken on the line III. III. ofFig. 2. yFig. 4 is an enlarged longitudinal sectional view of one of theunits, detached. Fig. 5 is aperspective view of one of the units partlybroken away.

Fig. (3 is a partial plan view-showing a modified construction ofattaching base.

The attaching base 2 of the device, as shown in the principal figures ofthe drawing, is formed of a longitudinal strip or piece of sheet metalof'suflicient gage and stifl'ness to maintain its form with sufficientresilience to provide ample cushioning actinn and application .to thesurface to be stamped, the strip 2 being deflected at each end providingterminals 3, 3, whichare secured to the end portions of a holding andoperating handle member 4. member, as shown, is a wooden bar to whichthe ends 3 of the strip 2 are secured in any suitable manner, as byconnecting screws although any suitable handle structure may beemployed, whereby to effect the desired functions. At suitable intervalslongitudinally of the strip 2, the opposite edge portions are cut orslit transversely for a short distance inwardly at each side providing.reccssed openings 6 with intervening outwardly projecting edge portions7.

The partly severed edge portions of the strip corres onding to theopenings 6 are bent inward y underneath the strip 2 at each side, asindicated at 8, the'recessed edge portions of the strip thus beingrounded, as indicated at 9, providing finished edges for attachment ofthe terminal lip portions of the printing or stamping units A. Theinwardly bent lips 8 also serve to stiffen or reinforce the edgeportions, thereby enabling lighter metal to be used, if desired, withthe accompanying advantage of reducing the cost and weight. By bendingthese parts inwardly, I avoid any projecting parts beyond the outer faceof the base.

The several units A are composed of a body portion a of rubber or othersuitable material which is molded around a sheet metal core portion 10in such a manner as to be firmly and permanently incorporated therewith.For such purpose theshcet metal core 10, which is of a flat strip 11, isprovided throughout its middle portion Wlth a plurality of closelyadjacent transverse openings 12.

The rubber stamping unit is made by molding the rubber entirely aroundboth sides and edges of the metal core for the main portion of itslength, the rubber extending integrally through the openings 12, fillin'them, as indicated at 13, and rnt1-. matel y bind-ing the opposite sideportions together and fixedly securing the rubber and metal immovablytogether. One end portion of the metal core 11 is bent inwardly formingthe angular lip 14 and adapted to engage around one of the rounded edges9 between the projections 7 at one side ofthe str p 2, the other endportion of the core being similarly bent inwardly, as indicated at 15,for the same purpose. The several stamping units are thus heldindividually in position, longitudinally of the base 2. As shown, thecore or base 11 of the stamping unit as pro- Said handle vided with anoutwardly deflected extended finger clip 16, for attaching or detachingthe unit. The rubber body portion of the rubber stamping member A isprovided at the side opposite such holding elements with'the outle'asing that end of t. e unit, whereupon it v maybe readily removed forsubstitution of another. 7

When desired, the curved holding base may be formed to provide aplurality of rows of unit attaching portions 2, 2, as

inFig'. 6, the space or spaces 6 between the outermost spaces 6, and incross alinement therewith, [being formed by slitting the 7 metalcrosswise and lengthwise to provide inwardl turnedlips 8', 85, shown indotted lines, orming similar rounded holding edges, as described, andspaces of ample width to receive the adjacent holding termiof a. ',plurality of rows of stamping I units." With such construction, the finger ofthe operator may be readily extended inwardly underneath the base, andeach par-. ticular unit released at will. With either construction Iprovide for positive and easy attachment and detachment of the stampingunlts and prevention of movement longitu-' dinally of thecurved base 2,by means of the lateral alternating projections and recesses ontheholding base and the co-acting terminals of the metal core 11 of thestampmg unit.

It will be understood that the size, design, arrangement, proportions orother details of the invention may be readily changed or modified b theskilled mechanic to suit speclal con itions of use, and that theinvention may be varied in different ways to provide for any specialarrangement or a plica-' tion of the stamping elements, but a ls'uchchanges are to be considered as within the scope ofthe following claims.

WhatIclaim is! I ,1. In a stamp, the combination of a holding handle, aresilient outwardly curved sheet metal base secured to each end of thehandle and arched away therefrom provided with laterallyextendingintegral projections and interve-mng recesses, and removable stampingunits having clip portions for enagement therewith, substantially as setorth.
